What if someone is not happy in marriage but staying together still and now finds his happiness might lie being away from the house but the person has 2 young kids. Does the person have a right to leave the marriage nd pursue his happiness? Also what if there is constant bickering and fighting home which is also not a good environment to raise a child. I would like some help in this case. Is an istekhara recommended?

Instead of walking out of the marriage, all attempts to reconcile the marriage should first be exhausted before ending the relationship
